So, it's been over 2 years since I started the wifi radio tutorial, and I'm starting to wonder about a couple things:

1. How much longer will the Wl-520gU be available? Does anyone know what the typical product lifespan for a wireless router is? I guess based on the WRT54G, something like 10 years?

2. Has anything better and/or cheaper come along since? I noticed recently that Newegg has the WL-500gP v2 for less than the WL-520gU. The WL-500 is a better option (aside from the size), so if I was buying a router today I'd probably go for that. But it's also 2+ years old. Are there any other options?

That's an interesting question. I've had a quick look at what's available right now, but the 520gU is still widely available and one of the cheapest options. I think the problem is that the market for routers with a USB port is just not very big, so very few new models in that category are released, especially in the cheap(er) segment. Also, we need decent OpenWRT support, and newer routers are very slow to show up in the supported hardware list. To top things of, the newer models don't seem to come with better/more powerful hardware and/or more flash memory. It just seems like wifi routers are quite a mature product, with very little innovation going on.

All in all, as long as routers like the 520gU and 500G remain available, I don't really see a need to start looking for something new.

I think that provided the WL-520gU and WL-500gP v2 remain available, the most obvious reason to find an alternative is to decode a wider variety of streams. I'm sure there are plenty of people in Britain who would like to be able to listen to the BBC via WMA or 3GPP (http://faq.external.bbc.co.uk/questions ... radiohowto). There seem to be some more powerful routers well supported by OpenWRT (the Buffalo WZR-HP-G300NH springs to mind). It is available in the UK for around £65 - more than the original, but with potentially greater value as a radio. My only detracting comment would be that it uses bizarre aerials that do not look easy to integrate into a custom design.

I may, if I find time, try to acquire such a router and attempt to emulate MightyOhm's excellent work, hoping to offer a wider range of stations to people. It's going to be tricky for someone who barely gets Linux, however!

I agree that a higher end option would be nice, particularly one that has much more onboard flash. Then again, at some point it probably makes sense to look at more sophisticated platforms, like some of the nano ITX boards that are out there...

Another option, albeit somewhat less compact, is to use a fanless mITX board. You should be able to find an older model EPIA board for not too much money (Although someone over on ebay seems to think they can ask $189 for one!). My EPIA 5000 currently serves as Asterisk server, but it would make an excellent internet radio: 500 MHz CPU, 256 MB RAM, and it boots from a 4 GB CF card using a CF2IDE adapter.

It's a little more expensive than the ASUS models, but it has 2x the flash and a somewhat faster CPU. Plus it is Draft-N capable. Don't mind the bad reviews on Amazon... they're because of the firmware from the manufacturer, not the hardware.
